help needed.

OpenStudy (tackopp):

Notice how 10.5/3.5 = 3 and 7.5/2.5 = 3 So those two corresponding dimensions tell us that the first is triple the second.

OpenStudy (welshfella):

Hint: the ratio of the sides of the larger pyramid to small pyramid should be 3:1.

OpenStudy (tackopp):

What do you think the answer is?

OpenStudy (welshfella):

- as Tackopp has explained.

OpenStudy (tackopp):

ratio of their dimensions is constant. we have PR/AC = PQ/AB = 1.25 but RQ/CB = 1.111 so RQ or CB has to be changed.

OpenStudy (hellokitty17):

but the question is asking for AB to be changed

OpenStudy (tackopp):

sorry misread

OpenStudy (tackopp):

the length of PR divided by the length of AC is one ratio. (that is the ratio of big to small of the "stair" side) find the number do the same for the bottoms: big divided by small and for the 3rd side

OpenStudy (tackopp):

A. change the length of side AB to 2 feet
